fThis invention relates to pipe joints of that class adapted to be automatically connected and 4disconnected at Will.' u Y An object of the invention has been to pro- ,5 vide in simple form a strong, serviceable and tight'V joint suitable4 for the conveyance of iiuids andrequiring no'manual attention other than an occasional inspection to assure the proper Jfunctioning 'of the device. f lo A Another object of the invention is to provide a pipe joint that Wil-l automatically cut 0E the source of iiuid supply and prevent the escapethereofpwhen the joint is lno ken. Another object of the invention is to ,prof

lvide a pipe joint that will automatically open i the main supply 'when the joint is made and connected. l i l j l -f` 'Another object of the invention is to provide a joint of this yclass wherein allexpa'n/ sion and contraction is taken Careoithus 'as-f suring perfect alignment .of v,the members" when connecting. j f. Y 1

The invention is yparticula'rly adapted' forV useon bascule vand[swingbridges and such like structurescarrying Water and gas mains andfconduits, and in which lit 'is necessary tof shutoiiQ the supply beforethe bridgecan be. opened. y Theiinvention is designedas animprovement onmy Canadian PatentNd 289,942,y 'ranted May 28,1929 and several importantL eatures not found in my previous inventionA are incorporated herein.4 a j l The important features of V.the invention are the means "of disconnecting the pipe-,line bythe openingmovement of the bridge and;

automatically shutting 0E the Iuid supply the means provided to prevent the escape o A,- the fluidV in thatportion of the line disconnected from the main line', andthe re-estabf lishing of pressure-tight connection in the pipeline bythe closing of the bridge: and

automatic turning on of 'the lfluid supply.

The invention consists essentially 'of a malef and 'female memberf in a pipe `line adapted to be broken or disconnected;` sueh'as'would, occur when installed upon' a bridge 'withv a' bascule lift orswingspan, one part ofi-Which,
